. Houle? A"Toall whom 'it may coneem: v Be itdt'nown that I, DAY-1n E. Tixonnr, a '."eitienqof theeUnited States, residing at 'N arshall, fin the county of Clark and State. otllliiiois, have invented certain new and useful Improvements in Concrete-Molds, of `Whieh,the'icollowing is a specification.

My intenti-'onrelates to certain new and .nset'ul ilnprorei'nents in concrete molds, and partleiiiarly -to inolds for hollow concrete,

A further object of lny intention is to prov le a structure 'of this cha aeter which ismsnnile in Construction and Composed oit' teit pai and one'in which the adjustments may he r'ea'dil),T made and the molds readily .,fplaeed'fin pesitionfor use and afterward renio'red therefrom.

In order to braee the. inolds againstfthe wall of eeinent l Apreterabl;7 proride at eaeh end of the inold a pair of'bars lSpiYoted together intermediate their ends by means of the pivot 19, the ende ot' theybars being also perforated and being adapted toA be .secured by means "of pins Q0 to' thebttoni and end' portionsof the inold.- The pins 2() pass through openings, Q1 in `the.

Securedgto the ends of the bars 21.l however, as by pins 24, are the straight sections 25 formed of L-irons, said. sections pair -of bars extending from. the bars 42 to l the overlapping portions o the bars 37 and -throu h which pins 27 may be passed to se- 13 and 38 and'14, Where they are connected cure t e bars to the down-turned ends 9 and 10u By placing pinslthrough various comextending etween the uprights 42 and held bmations of the openings 1n the ends 9 and in position by means of the hooks 47, its ends abutting against said uprights. may be adjusted. The root` of the arch 1s shown as braced b means of the bars 28, through one end o which' pass the pins 27, the ot er ends being connected by means ot' 15 pins 29 to the bars 7 `and 8. By providing a series of perforations 30 in the bars 7 and S for the in 29to 'engage the bar a single length obar 28 may be used for the various adjustments of the height of the mold. also provide a central support- 22 as is used V,in connection with the form shown in Fig. 1. In the form ofinvention shown in Fig. 3 .the bars 21, 22 .shown in Fig. 2 are used together with the end bars 25, 25 to which 25 the bars 21, 22 are secured by means oi' the pins 24. Instead, however, of the bars 7 and 8 Iprovide curved bars 30, 31, the lower ends oflwhich vare connected to the bars 25 by means lof the `pins 20 described in connection with Fig. 2. The ends of the bars 30 and 31 abut and are connected together by the plate 17 and pins 16' passing through. it and openings 32 in the bars 30 and 31. In this construction it will be seen that the mold has an' arched roof and both the height and vWidth of the, mold may be varied. In order to brace the structure I have shown a air of bars 33 pivoted together intermediate theirends 34 and adapted to be connected by means of the pins 35 to the openings 26 and also to be connected to the bars 30, 3l by means of the pins 36.

Referring now to ther form of construction shown in Fig. 4, the floor section as shown is formed by using a pair of bars 11, 12 adjustably connected together by means of the pin 16, to the upturned ends 13 and 14 of which are connected the ends of the pair of bars 37, 38. In this form of construction the central portion of the roof is formed fiat, and in order to effect this I provide a pair of bars 39, 40, provided with perforations 41, their overlapping ends being adjustably connected together, and the opposite ends connected to the bars 37 1Witnesses: and 38 by means of the pins 16. In order E. EMERSON,

to brace this structure I have shown the H. It. SNAVELY.

it will be seen that I have provided a mold section which is simple in construct-ion an which may be' readily adjusted to various sizes. It is to be understood of course in operation a plurality of these sections are set up, and that they are covered with suitable sheathing o Wood or metal, and that the concrete or the like is then tam ed into position around the mold so. forme in the ordinary manner. After the concrete is set theI sections can readily be taken down and removed.

I realize that considerable variation is possiblev in the details of construction and arrangement of parts without departing from the spirit oi my invention, and I thereforel do not intend to limit myself to the specific form shown and described.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: l

A mold comprising a pair of members provided with openings in each of the rims, pins adapted to be passed through the openings to join the members adjustably together at one end to form the roof of the construction to be molded, the other ends of said members being down-turned to form' the sides of the construction, asecond lpair o' members provided with openings at each of their' ends, pins for adjustably connecting the adjacent ends of said members together to form the vdoor of the construction tobe -molded. pins Jfor adjustably connecting the ends of the second mentioned members to the down-turned ends of the {irst mentione members, and united crossed braces connecting the interior portions of said members to their overlapping lateral portions.

In testimony whereof I ailix my signature in presence of two Witnesses.
